OILER.

Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed November 18, 1912. Serial No. 731,943.

To all whom it may concern:

Be it known that I, OsoAR ZERK, a subject of the Emperor of Austria-Hungary, residingat Cleveland, in the county of 'Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Oilers, of which the following is a full,

screwed into a threadedvopening, an em-' bracing cap therefor having an oil aperture, and an internal spring adapted normally to hold the cap with its aperture opposite the solid Wall of the first mentioned member, while allowing the movement of the cap to carry the aperture beyond the end of the stationary member, enabling the insertion of the point of an oil can and the discharge of oil into the tubular member.

The invention comprises such combination of members, and also the more particular embodiment shown in the drawings hereof, which has additional features of advantage, to be hereinafter described.

In the drawings,'Figure 1 is a perspective view of my oiler; Fig. 2 is a sectional side elevation thereof, the stationary member being shown in side elevation and the cap and spring in section; Fig. 3 is a longitudinal section of the device with the cap in the oiling position, instead of the normal position shown in the other two figures. .Fig. 4. is a detail of the parts forming the cap before they are fastened togetherthe body being shown in side elevation and the top in section.

As shown in the drawings, 1 represents a stationary or body member of my oiler. This is shown as a tubular member having, in its interior, a cylindrical bore 2 and on the exterior threads 3 near the lower end,

and above this an angular or hexagonal porthe exterior of the body furnishes means for the engagement of a Wrench to screw the body into place, with the threads 3 occupying the usual threaded opening.

10 and 11 in the drawing represent the cap of the oiler, this cap having a partially spherical -or mushroom shaped top 10, and a cylindrical wall 11. The top extends beyond the wall, as shown at 12, giving a neat and artistic appearance to the cap. The cylindrical wall 11 embraces the enlarged cylindrical portion 6 of the body and makes an easy slidingconnection therewith. At its lower end the cylindrical wall 11 is flanged or curled inwardly, as shown at 13, to substantially abut and make an easy sliding connection with the cylindrical portion 5 of the body. 7

Between the curled-in edge 13 of the cap and the shoulder 7 on the body, which comes between the cylindrical portions 5 and 6, is a helical compression spring, designated 20. This spring tending to expand, normally holds the cap in the position shown in Figs. 1 and 2. The cap is provided with an oil aperture 14, which, in the normal position of the parts, stands opposite the cylindrical body wall 6 and is closed thereby. WVhen, however, the'cap is raised against the action of the spring 20 into the position shown in Fig. 3, the oil aperture 141 is uncovered, and an oil can may beinserted through the same and thereby discharge oil into the bore 2.

To enable the oil aperture 14 to be easily foundby the point of the oil can, I bow upwardly the overhanging top 12 of the cap above the aperture, as shown at 15. The slight recess thus provided furnishes simple means for finding the oil aperture. The point of the oil can is placed against the overhanging flange 12 at any point and shifted around the cap until it comes into the recess 15, which the operators hand will readily detect by the slight jar on the oil can point. Then the oil can point is raised and raises the cap with it into the position shown in Fig. 3, and then the point is projected'into the interior to supply oil to the bore 2. w

The whole movement of locating the recess 15, raising the cap and inserting the point of the can may be done so easily and simply as to be, in efi'ect, one movement, of the operator. As. soon as. the oil has been discharged from the can, the point of the can is withdrawn and the cap returned to normal position.

My oiler, consisting simply of the three partsbase, cap and springis very cheap to produce. The base may conveniently consist of a single stamping, and such is the form in which they are shown in the drawing. The cap is preferably made" of two stampings, stamped together. Thus, as illustrated Fig. l, the body portion of the cap 11 may have an outward flange 17 and the top 10- be provided with a wall 18 which is adapted to surround the flange 17 and be pressed thereon to embrace it, as shown in Figs. 2 and 3. In assembling the parts, the base spring are put: into the cap before the lower edge of the cap wall is curled inwardly, and then the inward curling of the edge completes the assemblage.

lVhile I do not intend to limit myselilto any particular size of oiler, I may say that I have found it frequently convenient to make the oiler considerably smaller than shown in the drawings, the parts being enlarged in the; figures for convenience of illustration. The simplicity of my oiler adapts it for embodiment in small sizes, if de sired.

Having thus described my invention, what I claim is:

- 1. In an oiler, and in combination, a substantially cup-shaped body having a discharge opening in its bottom, a cap slidably mounted on the body and provided with a sidewall having an inlet opening normally closed by a part of the sidewall of the body, and a spring located externally oi the body and coeperating therewith and the cap, substantially as described.

2. In an oiler, and in combination, a sub stantiallycup-shaped body having a discharge opening, a, capslidably mounted on the body and provided with a side wall having an inlet opening normally closed by a part of the side wall of the body, and a spring located externally of the body and to one side of said opening, said spring cooperating with the body and cap, substantially as described.

3. In an oiler, a cap having a cylindrical side wall provided with an opening therethrough near 0116 6Il(l of the same, a. body having a part closely fitting within said side wall of the cap, and another part of relatively smaller diameter, and e a spring surrounding said part. of relatively smaller diameter and c'oeperating at one end witha shoulder formed by the part of larger diameter, and at its oppositeend with the end of the cap opposite to that adjacent ;c-ylindrical portion below the head, an angular portion below said smaller cylindrical portion, and an externally threaded portion below the angular portion, a cap having a top and a cylindrical wall slidably embracing the head of the body, a helical compres-' sion spring surrounding-thesmaller cylindrical portion of the body and com-pressed between the larger cylindrical portion and an inward projection on the cap, and an aperture through thecyli ndrical wall of the capadjacent to the top thereof. 7

5, In an oiling device, the combination of a bodyportion, a slidab-le cap thereon,- an opening through the wall oi the cap, a spring tending to hold the cap in position with the opening closed,- the cap having an overhanging edge by which it may be raised to free its opening, the overhanging edge of the cap having a recess adjacent to the opening for locating the point of an oil can with reference thereto.

6. In an oiling device, the combination of a bodyhaving a bore a cylindrical head and below that a smaller cylindrical portion, a cap having a cylindrical Wall embracing the larger cylindrical portion and turned inwardly at its lower edge to substantially abut the smaller cylindrical portion, a helical compression between such turned-in edge and the larger cylindrical portion of the body, the cap having a top overhanging the cylindrical wall, an oil opening through the c-ylindrical 'wall adjacent to the top and normally'opposite the a stern hollow throughout its'leng-th and having its outer end of greater diameter than the portion adjacent'thereto, of a sliding cap surrounding said stem and having its outer end closed, said cap being provided with an openingadanted to be brought into communication with the interior of said stem, the inner end of said cap being turned over to prevent its removal from the stem.

8. In an oil cup, the combination with a stem hollow throughout its length and having its end of greaterdiameter than a portion adjacent thereto, of a sliding cap surrounding said stem having its outer end closed, said cap being provided with an opening adapted to be brought intocommunication with the interior of said stem, the

inner end of said cap being turned over to In testimony whereof, I hereunto afiix my prevent its removal from the stem, and a signature in the presence of two Witnesses.
